FOOTWEAR.

This application is a division of copending application Serial N 0.743,140, filed October 11, 1924. I r

This invention relates to boots and the like of the kind in which themargin of the insole is bent upwards so that the tion of the same can beplaced middle porflat against the outer sole without any interveningfilling material.

In known boot constructions of this kind,

the insole is channelled to form for connection to the welt, and

sewing lips only the comparatively narrow sole margin which is thinneddown by the channeling bends up wards in a gradually developing curve.

The object of the present inv ention is to produce an inner boot surfacewhich is more in conformity with the natural shape of the sole of thefoot and presents to the latter a substantial concavity in which it iscomfortably supported, and the invention consists 1n strip of triangularcross-section between the two soles immediately behind the sewing lip.The sewing lip is moreover composed of a strip which is cemented to theinsole so that the latter can be made of thin material the better toadapt itself to the formation of the cavity.

Fig. l of the accompanying drawings represents a cross-sectional outlineof the foot and shows the angular posltion. of the insole margin.

Fig. 2 is a cross-section of the boot, and Fig. 3, a horizontal sectionof the same.

The insole 6 of with a margin 2 the boot or shoe 9 is formed which isinclined relative to the middle portion 1 at an angle of about 20.

The width of 0 of the widest portion but the width as well as the marginrepresents from of the sole,

the inclination may vary slightly according to requirements at differentparts of the same sole.

The margin is bent up so as to present a distinct boundary line 4 whichusually, i. e., when the boots are right and left sided, extends rightround the sole from and to the inside 3 where the margin merges dlrec ofthe waist tly into the the central body portion and in CzechoslovakiaOctober 19, 1923.

middle portion. In boots made -on straight lasts, the distinctionbetween the margin and the middle portion is omitted at both sides ofthe waist.

The insoles are planned out systematically, the same proportions ofmargin relative to the middle portion being maintained for'all thedifferent sizes.

Fig. 1 illustrates the position ofthe margin relative to the footIt andabove its inclination a relative to t-heundersurface p of the sole ofthefoot. r

The sewing lips whereby the insole is con nected to thewelt, arecemented to the insole which can therefore be made of thin'rnaterial.The middle portion 1 of the insole bears directly on the outer sole'7,andwedgeshaped strips 5 of cork, leather or the like are inserted tofill up the gap left behin-dthe sewing lip between the mar in 2 and thesole 7 Although shown in connection with a welted shoe, the features oftheinvention are also applicable to other kinds of shoes and boots.

claim V 1. In boots and shoes of the character clescribed, an insolehaving an inclined margin of a width representing from to 4' of thewidest portion of the insole extending right round the latter except atthe inside of the waist,-said margin being inclined so as to present aconcave surfacetothe foot.

2. In boots and scribed, an insole having an inclined margin of a widthrepresenting from to 4 of the widest portion of the insole extendingright round the latter except at the inside ofthe waist, said marginbeing inclined relative to the body port-ion of the sole at an angle ofabout, 20 so as to present a concave surface to the foot. i I

3. The insole structure claimed in claim 2, a sewing lip cemented to theunderside of the inclined margin, and a supporting strip of shoes ofthecharacter 'detriangular cross-secti0n arranged on the mar the freeedge of the sewing lip being flush with of the insole. In testimonywhereof I have signed my name to th1s specificatlon.
